DYNAMIC PLANNING AND MULTICRITERIA SCHEDULING OF TURNED PARTS' PRODUCTION

Technical innovations in the area of manufacturing logistics are being introduced partially and thus not exploiting their full potential. In order to optimise the efficiency of turning manufacturing processes, the process has been analysed and fundamentally re-engineered. All data from production (operations, quantities, date, time duration of operations, etc.) are now located in ERP system. It provided the necessary condition for the establishment of a robust dynamic planning model. An update was required for the whole lifecycle of products and means of work. The paper presents the information support and an algorithm for a dynamic planning model, based on a genetic algorithm. Continuous data capturing and planning in real time are a breakthrough in the management of the process. Presented are a generalised dynamic planning model and a case example from the production of turned parts, which take account of the singularities of a real environment. Production capacities have to be linked up with the supply chain and customers. The presented dynamic planning model can be adapted to various types of production.Original Abstract: U podrucju proizvodne logistike tehnicke se inovacije uvode parcijalno te se ne koristi njihov puni potencijal. U cilju poboljsanja efikasnosti proizvodnih procesa tokarenja, postupak se analizirao i u potpunosti preradio. Svi se podaci iz proizvodnje (operacije, kolicine, datumi, vrijeme trajanja operacija itd.) sada nalaze u ERP sustavu. On je osigurao potrebne uyjete za stvaranje modela dinamickog planiranja. Trazili su se azurirani podaci o cijelom radnom vijeku proizvoda i sredstvima za rad. U clanku se predstavlja informaticka podrska i algoritam za dinamicki model planiranja, zasnovan na genetskom algorittnu. Stahio dobivanje podataka i planiranje u realnom vremenu predstavljaju vazan napredak u upravljanju tim procesom. Predstavljen je generalizirani model dinamickog planiranja i primjer iz proizvodnje tokarenih dijelova gdje se uzimaju u obzir specificnosti stvarnog okruzenja. Proizvodni se kapaciteti moraju povezati s nabavnimlancem ikupcima. Ovaj se model dinamickog planiranja moze adaptirati razlicitim tipovima proizvodnje.
